MECHANICAL MOVEMENT.

Specification of Letters Patent.

Patented Feb. 22, 1921.

Application filed March 22, 1920. Serial 1%. 367,769.

To all whom it my concern:

Be it known that I, CHARLES KRUSE a sun Luis Obispo, in the county of San Luis Obispo and State of California, have invented certain new and useful Improvements in Mechanical Movements, of which the following isa specification.

This invention relates to mechanical movements, and the primary object of the invention is to provide an improved means for changing reciprocatory movement into rotary movement or vice versa.

Another object of the Invention is to pro vide an improved means for changing reciprocatory movement into rotary movement or vice versa, in which all danger of dead center as experienced in the crank shaft is avoided, and in which power will be trans mitted continuously to the work during all phases of the movement.

A further .object of the invention is to provide a mechanical movement which whenused in connection with internal combustion engines or the like will eliminate all trouble now experienced with crank and wrist pin connections and eliminate the uneven wearing of the piston and cylinder.

A further object of the invention is to provide an improved means for connecting the bearing bolts for engaging the sliding plate with the disks carried by the drive shaft, so that the pins can be readily removed without displacing the disks when it is desired to replace the bearings by the olts.

A still further object of the invention is to provide an improved mechanical movement as above specified, which is durable and eflicient' in use, one that is simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

With this and other objects in view, the invention consists in thenovel construction. arrangement and formation of parts, as will be hereinafter more particularly described, claimed and illustrated in the accompanying drawings, in which drawings:

Figure 1 is a vertical sectional view through an internal combustion engine showing the improved mechanical movement applied thereto, the piston being shown in a raised position.

Fig. 2 is an enlarged fragmentary vertical section through the lower portion of the engine, the piston being in its lowered position, and

3 is an enlarged vertical transverse section illustrating the means of connecting the slldeplate with the shaft carried disks.

Referring to the drawings, in detail, wherein similar reference characters designate like and corresponding parts throughout the several views, the letter A indicates the mechanical movement, which is shown 1n connectlon'with an internal combustion engine B, but it is to be understood that the same can be effectively used with other devlces.

The internal combustion engine B is of the ordinary or any preferred type and includes the cylinder 5 having reciprocably mounted therein the piston 6 rigidly carrylng the piston rod '7. The cylinder 5 is connected to the'shaft casing 8 in the ordinary manner. The shaft casing 8 is relatively narrow in cross section, and includes the straight vertical side walls 9 which form guides for the slide plate 10 of the mechamcal movement A which will be heremaftermore fully described. The casing 8 rotatably supports the drive shaft 11 which has keyed or otherwise secured thereto the usual balance or fly wheel 12. The side walls 9 have formed thereon the spaced ribs 13 which engage the opposite sides of the slide plate 10 and prevents relative lateral movement of the same in relation to the side walls.

The mechanical movement A as stated includes the slide plate 10 which is of substantially rectangular configuration and is pro vided with the vertical side faces 14, which slidably engage the inner faces of the side walls 8. The slide plate 10 is provided with the diagonally extending slots 14 and 15, which bisect each other at the central portion of the plate. The plate 10 is further provided with a slot 16 which is positioned the plate 10 and these disks have eccentrically secured thereto the transversely extending cross bolts 19 and 20, which slide respectively in the slots 14 and 15. The

bolts 19 and-20 are located at substantially right angles to each other in reference to the axes of the disks 18 and these bolts carry the central bearing sleeve 21, and the end sleeves 22. The central bearing sleeve 21 is provided, so as to permit the free movement of the bolts in the slots, and the end bearings 22 are positioned in suitable openings formed in the disks 18, and prevent displacement of the central bearing sleeve. The bolts 19 and 20 are secured in place by suitable nuts 23, which engage washers 24 which engage against the outer face of one of the end bearings 22 and'one, face of one of the disks 1 8. The washers 24 prevent dis lacement of the bearing sleeves.

' Ifroperation of the improved device, the bolt 19 slides in the slot 14 while the bolt 20 slides in the slot 15, and the inclined faces of these slots bear against the bearing sleeves of the bolts, and slide the bolts in the slots, and thus turn the disks 18, whicnin turn. transmit their motion to the drive shaft 11. As clearly shown in Fig. 1 of the drawings, when the piston is on its down stroke, the inclined up er face, of the lower half of the slot 15 wil engage the bolt 20 and tend to push the same out of the slot. This is owing to the inclination of the upper wall of'the slot. Simultaneous with the movement of the bolt 20 toward the outer end of the lower half of the slot, the bolt 19 moves into the upper half of the slot 15 and the. upper inclined wall of the same engages the bolt and slides the sametoward the inner end thereof. This rotates the disk and ides-the bolt 20 into .the upper half of t e slot 15, at which time the piston will be on its up er stroke, and the lower inclined base 0 the upper half of the slot 15 will engage the bolt 20 and slide the same inwardly, and turn the disk and move the bolt 19 into the lower half of the slot 14, and the lower inclined base thereof will move the bolt toward the inner end of the slot. This will turn the disk and again move the bolt 20 into the lower half of the slot 15 and the upper inclined face thereof will move the botl 20 toward the inner end of the slot and turn the disk a portion of a revolution and move the bolt 19 again-into the upper half of the slot 14 where the upper inclined surface will act on the bolt. 19 and move the bolt 20 into the upper half of the slot 15 as clearly shown in Fig. 2 of the drawings. This completes one revolution'of the shaft, and on the next explosion of the engine, the shaft will be turned in the same manner.

.From the foregoing description, it can be seen that animproved means is provided for transmitting reciprocatory movement into rotarymovement or viceversa, which can be efi'ectivel used for internal combustion eng nes an the like.
